MOUNTED DRAFTlNG-SHEET..
SPECIFICATION forming part of Letters Patent No. 551,003, dated December 10, 1895.
Application filed March 2, 1895. seria No. 540,238. (No specimens.)
To @ZZ whom it may concern,.-
Be it known that we, WILLIAM E. SAW- TELLE and EDWARD W. SHEDD, of the city and county of Vorcester, in the State of Massachusetts, and OLIVER PERRY SABLE, Jr., of
the Ycity and county of Providence, in the State of Rhode Island, citizens of the United States, have. invented a new and useful Mounted Drafting-Sheet, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.
The object of our invention is to provide a durable drafting-sheet suitable for assessors, city engineers, or corporation maps and for similar uses where original maps or delineated plans require to be frequently handled and used, as in the city departments, which sheet will efficiently stand the uses Without becoming warped or bent and which will not cleave nor be injuriously affected by changes of humidity in the atmosphere or the various climatic changes to which it may be exposed. These objects we attain by the mounted drafting sheet constructed as hereinafter eX- plained.
In the drawings, Figure l is a front View of our mounted drafting-sheet. Fig. 2 is a perspective sectional view illustrating the construction, and Fig. 3 an enlarged vertical section through one edge of the sheet.
Our mounted drawing-sheet consists of a ber-board body composed of heavy bookboard or tar-board prepared with a waterproofing or moisture-resisting coating or surface lm applied upon both sides and having attached to its face a sheet of drawing-paper suitable for delineation thereon of the map or other drafts by the ordinary drafting methods, said face being uniformly and permanently attached to said body by a waterproof or non-absorptive adhesive substance, and the whole reinforced or bound about its edges with a metal binding folded over and embracing the body and facing With a clinch-grip, the binding being preferably provided with narrow intervals that allow slight expansion and contraction.
The process of makingthis new article of v manufacture is as follows: IVe take thoroughly-seasoned fiber-board A, preferably that known in the trade as No l tar-trunk board, of about one-eighth inch, more or less, or, say, No. 9, in thickness, and of the required superficial dimension, say twenty-six by thirty-eight inches, more or less. This liberboard we prepare by thoroughly coating it upon both sides with a moisture-repelling coating C, of orangeor white shcllac. lVhen this is dry, we add a second coating O on one side and thoroughly dry the same. We then apply tothe other side a further coating of the shellac F, and before it sets or hardens lay thereon a sheet of drawing-paper D, preferably of the kind known as VVhatnians cold-pressed, and rub the same down thoroughly to make it uniformly adhere to the body by the intervening impervious lm of shellac. A heated smoothing-iron is then passed over the face of the sheet, rendering the delineating-surface uniformly smooth and insuring the rm integration and adhesion of the adjacent fibrous surfaces and intervening moisture-repelling lm. The edges are then trimmed square and even and a metal binding-strip B is compressed onto the edge in the form shown in Fig. 3, binding the body and facing together and forming a protectingguard that prevents abrasion of the edges by handling and rough usage. The corners e are preferably rounded, as shown. The binding is best formed of incontiguous sections or made with narrow spaces b in the straight sides, which allow slight expansion and-contraction without straining the binding at the corners of the sheet.
If desired, the eld of the sheet may be squared or made with the edges at the sides and ends at right angles to each other, so that a draftmans T-square can be used directly upon the edge of the mounted sheet.
These drafting-sheets, made as shown and described, are of great practical utility for maps and plans such as used in the city departments and for similar purposes, as they are very durable and can be handled with facility, set up on edge in racks, and subjected to much and severe usage and to the changes of humidity and temperature without becomin g warped distorted, damaged, or torn, while alterations and additions to the delineations thereon can be ina-de at any time with ready facility.
That We claim as our invention, and desire to secure by Letters Patent, is
l. A mounted drafting sheet, comprising a body oi fiber-board having an iinperviously coated exterior, a facing of drawing paper, an intermediate inoisture-repelling filln attaching said facing to the body, and a metal protector or binding secured upon the edges of the sheet.
2. In a mounted drafting sheet, the coinbi nation with the iber-board body and facing of drawing paper attached thereto, of the metal binding folded upon and attached to the edge by a clinch grip, said binding being formed of incontiguous sections, or with narrow open spaces at the respective straight sides of the sheet, for the purpose set forth.
8. The mounted drafting sheet, composed of a thick fiber-board body preparatively coated upon both its top and bottom surfaces with shellae, a delineating surface formed of drawing paper laid upon and attached to said body by a second applied film of shellac, its face inade flat and even by pressure applied while such shellao is in soft condition, and having its field made square and its edges bound with a protecting strip folded upon and confining the body and facing together, substantially as described.
fitness our hands this 27th day of February, A. D. 1895.
